Free Communications Over Free Radio Bands

What's in this site?

  • My homemade antennas for the European Free Bands (without license) covering CB, PMR446, SRD869, WiFi 2.4 GHz
  • My experiments of Long Distance Communications with Low Power Radios (QRP) over CB, PMR446 band, SRD869 band, WiFi 2.4 GHz band up to Infrared, red LED, LASER and... why not, experiments with GPS receiver, with Satellite TV and with solar rays for cooking with Solar Owens
  • Study of homemade antennas with 4nec2 free software
